A perceptron consists of weights $\left[w_{1}, w_{2}, w_{3}, w_{4}\right]=[0.5,2,1,-3]$. The activation function is provided as $y=f(z)=1$ if $z \geq 2$ otherwise $0,$ where $z= \sum(w . d)$. What is the output $y$ for the following four data samples $d?$
$$\begin{array}{|c|c|c|c|c|}
\hline & p_{1} & p_{2} & p_{3} & p_{4} \\
\hline \hline d_{1} & 1 & -1 & 0 & 1 \\
d_{2} & 1 & -1 & 1 & 1 \\
d_{3} & 0 & 0 & 1 & -1 \\
d_{4} & 1 & 0 & 1 & -1 \\
\hline
\end {array}$$
